Legal claims defining the scope of protection, as filed with the USPTO.
1. A method to hot-plug a module into the chassis of a server said method comprising: (a) determining fabric type of modules already in the chassis when the module is being hot-plugged, said fabric type corresponding to a transfer method of data to and from routing components; (b) determining fabric type of the hot-plugged module; and (c) correlating fabric types in (a) and (b) to determine which power permission state to apply to the hot-plugged module, wherein said power permission state is determined from among granting permission to power on the hot-plugged module and not granting permission to power on the hot-plugged module.
2. The method of claim 1 , wherein the hot-plugged, module is permitted to power on if the correlation indicates the fabric type of the hot-plugged module to be identical to fabric type of already installed modules that have been given power permission.
3. The method of claim 2 , wherein said power on of the hot-plugged module includes providing the hot-plugged module with a pre-set power input that is received by each component that is connected to the chassis via the fabric type of the modules already in the chassis and powered on.
4. The method of claim 1 , wherein power is denied to the hot-plugged module if correlation indicates conflicting fabric types between the hot-plugged module and already installed modules that have been given power permission.
5. The method of claim 4 , wherein the modules include blades, and said determining includes: instantiating messages between a control software management module and a network swicth; and issuing messages to said blades to obtain information of the blades' peripherals, including a comparison of established fabric types associated with the blades.
6. The method of claim 4 , wherein the modules include interconnect devices.
7. The method of claim 6 , wherein the interconnect device includes network or connectivity switches, wherein said switches are electrically and mechanically keyed substantially similar to each other.
8. The method of claim 4 , wherein the fabric type includes one or more of Ethernet and fibre.
9. A server including: a chassis with at least one blade and at least one interconnecting device fully powered; at least one module hot-plugged into said chassis; p 1 a controller to determine fabric type of the blade, the module and the interconnecting device, said fabric type corresponding to a transfer method of data to and from routing components; and said controller permitting power to be applied to said at least one module if all fabric types are compatible and denying permission to add power to said at least one module if the fabric types are incompatible.
10. A method to power modules in a server, said method comprising: (a) using a first routine to apply full power to modules inserted in said server before power-on; (b) hot-plugging a module into a slot of said server subsequent to power-on; (c) determining fabric type of modules in step (a), said fabric type corresponding to a transfer method of data to and from routine components; (d) determining fabric type of hot-plugged module in step (b); (e) correlating fabric types determined in step (c) and step (d); and (f) depending on results of the correlation in step (e) determine a power permission state for said hot plugged module, wherein said power permission state is determined from among granting permission to power on the hot-plugged module and not granting permission to power on the hot-plugged module.
11. The method of claim 10 wherein the module includes a blade.
12. The method of claim 10 wherein the module includes a connector.
13. The method of claim 12 wherein the connector includes switches.
14. The metbod of claim 13 wherein the switches include ethernet.
15. The method of claim 10 wherein full-power is permitted to be applied to said hot plugged module if the fabric type of the hot plugged module is compatible with fabric type of modules inserted in the server prior to power-on that have been given power permission.
16. The method of claim 10 wherein full power is denied to said hot-plugged module if the fabric type of said hot-plugged module is incompatible with fabric type of modules installed in the server prior to power-on.
17. A program product including a medium on which computer readable program is recorded, said program including: (a) instructions to determine fabric type of a first set of modules, said fabric type corresponding to a transfer method of data to and from routing components; (b) instructions to determine fabric type of another module; (c) instructions to correlate fabric types in (a) and (b) to determine a power permission state to apply to the another module, wherein said power permission state is determined from among granting permission to power on the hot-plugged module and not granting permission to power on the hot-plugged module.
18. The program product of claim 17 , further comprising: (d) instructions for providing the hot-plugged module with permission to power on if the correlation indicates the fabric type of the hot-plugged module to be identical to fabric type of already installed modules that have been given power permission; and (e) instructions for withholding giving permission to power on to the hot-plugged module if the correlation indicates conflicting fabric types between the hot-plugged module and already installed modules that have been given power permission.
19. The program product of claim 17 , wherein: the first set of modules includes one of blades and include interconnect devices, such as switches; and the fabric type includes one of Ethernet and fibre.
